I'm almost wondering if powerful systems mess with FSX. I use FSX on a laptop, and FSX always works smoothly for me. I can set autogen at "Dense" and everything else at maximum, and the only time FSX crashes is when I take off from New York with a complex plane--pretty much anything from Captain Sim (but they work just fine elsewhere).

Hi Brian.

I have now given this a try for a couple of days and a few long haul flights. I don't recommend it. It worked OK with swapping add-on aircraft without causing a fatal error, BUT, it caused major problems for my more advanced payware add-on aircraft. I found some aircraft systems just weren't working correctly. For example:

On one flight, I was doing an autoland, I had the Autoland 3 lights up and all looked great. But as I got closer to the airport, something was really not right. I came screaming in for a landing at about VREF+40, hit the runway hard (no flare or thrust reduction). I then continued along the runway, Autobrakes were not working, reverse thrust not working, and in the end just stopped shy of the end of the runway.

Anyway, that's how I found it. I replaced the files and flew an identical flight without any problem.

Don't say such things, Lou. Makes me think about all the TWA passengers from back in the days.
Remember that video with the bumping plane lately?  

By the way, did you ever fly that old Kai-Tak approach in your career, Lou? Must have been pure fun for the residents with the loud 707 stuff passing by.
